Experiencing breakdowns or inefficiency?
Our expert team is ready to fix your air conditioning issues quickly and effectively. Reach out today for fast, reliable service and restore your air condition to its full capabilities!
We’ve answered some common questions to help you understand our services and how we can address your air conditioning needs.
If your air conditioner is blowing warm air, it could be due to a refrigerant leak, clogged air filters, or a malfunctioning compressor. You may also have a thermostat issue. It’s best to have a professional inspect the system to diagnose and fix the problem.
The cost of installing a new air conditioning system varies based on the size of the space, type of system, and complexity of the installation. On average, homeowners can expect to pay between £1,500 to £5,000. Commercial installations may cost more depending on the project scale.
The size of the air conditioner depends on the square footage of your space, insulation, and cooling needs. A professional can perform a detailed site survey to calculate the correct size, ensuring your system is both efficient and effective without unnecessary energy waste.
It’s recommended to service your air conditioning unit at least once a year to maintain efficiency, prevent breakdowns, and extend its lifespan. Regular servicing can help identify issues early, keeping your system running smoothly and reducing long-term repair costs.
Air conditioning systems generally last between 10 to 15 years, depending on usage and maintenance. With regular servicing and proper care, you can extend the life of your system, ensuring it performs efficiently and reliably for years.
You can improve the efficiency of your air conditioner by cleaning or replacing filters regularly, scheduling professional maintenance, sealing leaks in ducts, and upgrading to an energy-efficient model. Keeping the thermostat at a moderate temperature can also reduce energy consumption.
